The fact about Lantus stinging is TRUE.
the liquid carrier for Lantus is acidic.
the liquid carrier for Levemir is not acidic, but neutral
A human diabetic has told us that indeed, her Lantus shots sting compared to other insulins that she has used.
cost effectiveness:
Lantus is designed to be good for 28 days at room temperature "guaranteed" by the manufacturer. While it will last longer stored carefully in the refrigerator, many people replace the cartridge before finishing the insulin.
Levemir is designed to be good for 42 days at room temperature "guaranteed" by the manufacturer. This means you can use the entire cartridge before it goes bad if you store carefully in the refrigerator.
There are several documented studies in Veterinarian literature / journals about the use of LANTUS in CATS.
Not so with Levemir, but many people are using it for their cats with great results. It is very similar to Lantus is effectiveness, and I personally chose to use Lev over Lantus for the previously stated two reasons (stinging and cost/efficacy)
ALSO -- there is no specific treatment for Acromegaly that can be done by a regular practice vet other than helping with symptoms (pain, etc). There is SRS (stereotactic radiation surgery) done by CSU.
What the Acromegaly (IGF-1) diagnosis gives:
1> proof that your cat has a functioning pancreas -- diabetes is caused by pituitary tumor (this affects HYPO treatment!!!)
2> a reason for needing more insulin, and confidence that you are doing the right thing for your kitty by increasing the dose beyond what seems "reasonable"
3> a network of acromoms that can help advise / watch for related symptoms / recommend treatments that work and document treatments that didn't work
The IAA test is done by the same lab as the IGF-1 and costs $14. It is definitely money well spent to have both tests done from the same shipment of blood since shipping and blood draw are the biggest costs.
Hope this helps!

p.s. My vet refused to prescribe Lantus or Levemir in 2008. I eventually ordered Levemir from Canada with no prescription (before the law was changed). Later, I presented the cat (Tiggy), the spreadsheet of data, requested a fructosamine (result = Well Regulated) and requested that she write a prescription for Levemir cartridges (in 2010 after the law changed).
In 2009, my vet got a new client whose kitty was already on Lantus, so she finally did the research and realized what a good insulin it is. So.... when I requested the Levemir script -- she wrote it. The insulin is cheaper in Canada, and I am 35 miles from the border, so..... i make a road trip when I need insulin. It costs $110-120 for a 5-pack of Lev. (not including gas, tolls, etc)
